Reaction Steps

4-Cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylic acid [2-cyclohex-1-enyl-4-(2-oxo-hexahydro-pyrimidin-5-yl)-phenyl]-amide (as prepared in the previous step, 14 mg, 0.026 mmol) was dissolved in DCM (1 mL), EtOH (30 μL) and TFA (0.3 mL). The resulting mixture was stirred overnight and concentrated. The residue obtained was subjected to RP-HPLC eluting with 20% to 100% CH3CN in 0.1% TFA/H2O over 20 min on a C18 column to obtain the title compound (1.1 mg, 8%): 1H-NMR (CD3OD/CDCl3; 400 MHz): δ 8.23 (d, 1H, J=8.0 Hz), 7.90 (s, 1H), 7.20 (dd, 1H, J=8.0, 2.2 Hz), 7.09 (d, 1H, J=2.2 Hz), 5.75 (br s, 1H), 3.47 (4H, m), 3.17 (m, 1H), 2.22-2.33 (m, 4H), 1.72-1.83 (m, 4H). Mass spectrum (ESI, m/z): Calcd. for C21H22N6O2, 391.3 (M+H). found 391.2.
